Answer:
The angle between two forces is 165 degrees.
Explanation:
We have,
Force 1, 
Force 2, 
Resultant of two forces, F = 8 N
It is required to find the angle between two forces. The resultant of two force is given by the formula as follows :
is the angle between F₁ and F₂
So,
So, the angle between two forces is 165 degrees.
Explanation:
Webb gives us new and unique eyes of places that we have never been able to reach.” With NASA and the European Space Agency's Hubble pushing 32 years in orbit, the bigger, 100 times more powerful Webb is widely viewed as its successor even though the two are vastly different.
Answer:
7.85 cm
30 degree
Explanation:
As we know that that the angular displacement in one turn is 360 degree.
As there are 12 parts which are equally divided so the angle turn by each part is
= 360 / 12 = 30 degree
Thus, the angular displacement of each slice is 30 degree.
Radius of pie = 15 cm
Circumference of pie = 2 x 3.14 x 15 = 94.2 cm
Arc length for complete 360 degree = 94.2 cm
Arc length for 30 degree turn = 94.2 x 30 / 360 = 7.85 cm
They had to use thrust because there is no air on the moon meaning that parachutes would be totally useless because parachutes require air to create drag. Fun fact since there is no air on the lunar surface sound waves cannot be made since there are no air molecules for the waves to pass through, so that's why they use radio's in space.
Answer:
Two off-centered spots in the first phase of the experiment; one centered spot in the second phase of the experiment.
Explanation:
If two particles are selected in which both have the same electron mass and the same velocity, but one of the particles has a charge and the other particle has a charge of 2e. During the first stage of the experiment, the two particles have an electric force equal to F = Eq in the entire vertical direction. The acceleration of particle is equal to a = (Eq)/m.
In the second part of the experiment, the magnetic field cancels the electric field. In this way, the electric force and the magnetic force cancel each other out. Therefore, the net force acting on each particle is equal to zero.
Because these two forces cancel each other out, the particles fail to create two off-center points on the screen in the second part of the experiment. Also, if the loads are different, the deviation is also different. In this way, an off-center point cannot be achieved in the first part of the experiment. There will be two off-center points.
